Description

Urban railway signal through ground wire connector

Technical Field

The invention relates to the field of suitable-area railways, in particular to a connector for urban railway signal through ground wires.

Background

At present, a connector used for a through ground wire of a railway signal system in a city area is generally in a C shape and used for equipment grounding, the C-shaped connector is generally in a C-shaped buckle, a double C-shaped structure is connected between a main wire and a branch wire of the through ground wire to ensure that the main wire and the branch wire are tightly connected, however, the extending directions of the main wire and the branch wire of the through ground wire are not similar (the branch wire is a ground wire from equipment), and therefore the traditional connector has the defect that the branch wire needs to be bent and then fixed in the buckle together with the through ground wire to enable the main wire and the branch wire to be parallel, loss or burrs can occur to the ground wire, and meanwhile, the time cost of construction personnel is.

Disclosure of Invention

The invention aims to provide a city railway signal through ground wire connector aiming at the defects that the existing connector needs to bend branch wires, so that the loss is increased and burrs are generated.

In order to achieve the above purpose, the invention provides the following technical scheme:

urban railway signal passes through earth connection ware, including horizontal first main part, first main part is conducting material and makes, be equipped with first accommodation space and second accommodation space on the first main part, the extending direction nonparallel of first accommodation space and second accommodation space. The first accommodating space is used for accommodating the main line, and the second accommodating space is used for accommodating the branch line, so that the branch line can be prevented from being bent when being connected with the main line.

Furthermore, first accommodation space is in the connector link that the both ends of first main part all set up, the connector link orientation perpendicular with the direction of first main part extends, second accommodation space is in the connecting hole that sets up on the first main part. The connecting buckle is used for connecting the main line, the loads at the two ends are the same, the phenomenon of deviation cannot be generated, meanwhile, the connecting buckle is connected with the branch line through the connecting hole, the branch line does not need to be bent, the connection of the main line and the branch line can be realized, and the increase of loss and the generation of burrs are avoided.

Further, the bottom of the first main body is connected with a vertical second main body, and the whole structure after the first main body and the second main body are connected is T-shaped. So that the whole has better stability and is not cheap.

Further, the second body is made of a conductive material. For grounding.

Further, the second body and the first body are made of copper. Copper has a good texture and can prolong the overall service life.

Further, the connection buckle is configured in a C shape.

Further, the diameter of the connecting buckle is 34-38 mm. The same or similar size as the main line.

Further, the diameter of the connecting hole is 34-38 mm. The same or similar size as the spur.

Compared with the prior art, the invention has the beneficial effects that:

the invention adopts two connecting buckles to fix the main line, simultaneously uses the T-shaped structure, can obtain better stability without deviation, simultaneously uses the connecting hole to be connected with the branch line, directly connects the branch line to the main line, does not need to be bent, reduces the construction amount and simultaneously ensures more reliable grounding.

Detailed Description

The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.

The embodiment provides a city railway signal through ground wire connector for connecting a main wire and a branch wire of a through ground wire.

As shown in fig. 1-4, the device comprises a transverse first body 1 and a vertical second body 3, which are connected with each other, the whole body after connection is T-shaped, and the second body 3 is connected with the ground for grounding. Therefore, the first body 1 and the second body 3 are made of conductive materials, such as iron, aluminum, etc., preferably, both are made of copper materials, because the texture of copper is good, and the service life of the whole body can be prolonged.

Both ends of the first body 1 are provided with connecting buckles 4 (first accommodating spaces), the connecting buckles 4 are in a C-shaped structure, the extending directions of the two connecting buckles 4 are the same and are perpendicular to the first body 1, so that the two connecting buckles 4 are provided with intervals. The connecting buckles 4 are used for installing a main line penetrating through the ground wire, and when the ground wire connecting device is used, the main line is placed into the two connecting buckles 4 and then cold-pressed, and the main line is placed.

The diameter of the connector link 4 is 34-38mm, preferably 35mm, and the same size as the main wire, the reason why the connector link 4 is arranged in a C shape is that the cable cores are combined together in a layer twisting manner, and a layer of lead sheath is wrapped on the outer surface of the cable cores, so that the main wire is hard, and the connector link 4 is constructed in a C shape, and the main wire is not easy to be released, so that a better connection effect can be obtained.

The first body 1 is provided with a connecting hole 2 (second accommodating space) which is a blind hole, preferably arranged in the middle of the first body 1 and used for connecting a branch line penetrating through the ground wire, and when the connection is performed, the branch line can be connected with the main line only by inserting the branch line into the connecting hole 2 without bending. The diameter of the connecting hole 2 is 34-38mm, preferably 35mm, the same size as the branch line. Due to the soft texture of the branch line, a good connection stability can be obtained by the insertion method.

The invention is integrally constructed in a T shape, when the T-shaped branch line is connected with the main line, the loads at two ends are the same, the condition of deviation generated in the installation process is avoided, the branch line does not need to be bent, the installation is carried out according to the original direction of the branch line, and the increase of loss is avoided.
